How to use apps/transport/lib/transport/gtfs_diff.ex?

[dancesWithCycles]

Hi folks,
Thank you so much for providing and maintaining this repository.

I randomly stumbled over this readme file that leaded me to this source file.

It is the first time I come across Elixir. Do you mind providing an instruction set that describes how to use the GTFS Diff tool from scratch imagining a clear Linux operating system environment?

Example:

• prepare Elixir

cd
apt install curl git
git clone https://github.com/asdf-vm/asdf.git ~/.asdf --branch v0.14.0

or

git clone https://aur.archlinux.org/asdf-vm.git && cd asdf-vm && makepkg -si

Add the following to ~/.bashrc:

. "$HOME/.asdf/asdf.sh"

Completions must be configured by adding the following to your .bashrc:

. "$HOME/.asdf/completions/asdf.bash"

• install plugins

asdf plugin-add erlang (https://github.com/asdf-vm/asdf-erlang)
asdf plugin-add elixir

• get repo

cd
git clone [email protected]:etalab/transport-site.git
cd transport-site

• run Elixir tool

mix cmd --app  apps/transport/lib/transport/gtfs_diff.ex

Cheers!
